NNG_CLOCK(3supp)

📦 version 1.11, in alpine 3.24

💖 NAME 💖

nng_clock — get time. yes bestie, that is literally the whole name 😌 and this little icon is NNG_CLOCK(3supp) from the NNG Reference Manual 🫶

✨ SYNOPSIS ✨

#include <nng/nng.h>

typedef uint64_t nng_time;

nng_time nng_clock(void);

🎀 DESCRIPTION 🎀

okay so nng_clock() gives you the number of elapsed milliseconds since some arbitrary time in the past. not like a cute calendar date, just a reference point somewhere back there 💅

the resolution of the clock depends on the underlying timing facilities of the system. so like, your system's timing setup is the main character here, and it decides how fine-grained things get 🌸

this function may be used for timing, but applications should not expect very fine-grained values. periodt. it's giving "useful timer energy," not "precision nanosecond drama" 😭

Important: the reference time will be the same for a given program, but different programs may have different references. so don't go comparing raw clock values across programs like they're matching bestie bracelets, because they might not line up 🙈
Tip: this function should help with setting appropriate timeouts. very handy, very slay, very "now I know how long to wait" energy ⏳✨

💫 RETURN VALUES 💫

milliseconds since reference time. that's the whole return value, bestie — a uint64_t-flavored number of milliseconds 🫶

💀 ERRORS 💀

none. literally none. not a single error, no cap 😌
